1. INTRODUCTION

General

These instructions for assembly and use relate to assembly, modifica-
tion and dismantling of the Layher Zifa tower made by Wilhelm Layher
GmbH & Co. KG, of Güglingen-Eibensbach, Germany. The instructions
cannot cover all the possible applications. If you have any questions
about specific applications, please contact your Layher partner.

Caution: The Layher Zifa tower may only be assembled, modified and
dismantled under the supervision of a qualified expert and by techni-
cally trained employees.

2. GENERAL INSTRUCTIONS FOR
ASSEMBLY AND USE

The rolling tower may be used for the scaffolding group as specified
in DIN EN 1004.

The user of the rolling tower must comply with the following
instructions:

1. The user must check that the selected rolling tower is suitable for
the work to be performed (Section 4 of the German Ordinance on
Industrial Safety and Health - BetrSichV).

2. The maximum platform height is, in accordance with DIN EN

1004:2005-03
• inside buildings 12.0 m
• outside buildings 8.0 m

The ballasting and component requirements set forth on pages 8 – 10
and 26 – 27 must be complied with. Non-compliance leads to a risk of
accidents. Stability and load-bearing capacity are no longer assured.
Assembly variants diverging from the specifications may require addi-
tional design measures. In these cases, the stability and load-bearing
capacity must be verified for each individual variant.

3.  The  assembly,  modification  or  dismantling  of  the  rolling  tower  in
accordance  with  the  present  instructions  for  assembly  and  use  may
only  be  performed  under  the  supervision  of  a  qualified  person  and
by  professionally  suitable  employees  after  special  instruction.  Only

the tower models shown in these instructions for assembly and use
may  be  used.  The  tower  must,  after  assembly  and  before  being  put
into  service,  be  inspected  by  persons  qualified  to  do  so  (Sections  4
and  10  of  BetrSichV).  The  inspection  must  be  documented  (Section
11  of  BetrSichV).  During  assembly,  modification  or  dismantling,  the
rolling tower must be provided with a prohibition sign indicating "No
access allowed" and be adequately safeguarded by means of barriers
preventing access to the danger zone (BetrSichV Annex 2, para. 5.2.5).

4. Before installation, all parts must be inspected to ensure they are
in perfect condition. Only undamaged original parts from Layher's mo-
bile working platform systems may be used. Scaffolding parts such as
snap-on claws and spigots must be cleaned of dirt after use. Scaffold-
ing components must be secured against slipping and impacts when
transported by truck. Scaffolding components must be handled in such
a way that they are not damaged. For wall bracing and attachment of
ballast weights, see the table on pages 8 – 10 of these instructions for
assembly and use.

5. To assemble the upper sections of the tower, the individual compo-
nents must be passed up from one level to the next. Small quantities
of tools and materials can be carried up by the personnel, otherwise
hoisted to the working level using transport ropes.

6. The ladder frame joints must always be secured using spring clips.

7. The tower must be set to the perpendicular by inserting suitable
materials underneath it. The maximum divergence from the perpen-
dicular is 1%.

8. Stability must assured during each phase of the assembly process.

9. On intermediate platforms used solely for ascent, toe boards can be
dispensed with. For small towers where the height of the deck is more
than 1.00 m, equipment must be provided that permits attachment of
side protection in accordance with DIN EN 1004:2005-03.

10. Access to the working platform is generally speaking only permitted
on the inside of the tower. The exception to this is tower models having
a platform height of < 1 m.

11. Working on two or more working levels at the same time is not per-
mitted. In the event of exceptions, the manufacturer must be consulted.
When work is done on several levels, they must be completely equipped
